Sharing a iPXE script (using wimboot) I am using these days along with Tiny PXE Server to boot winpe over the network on multiple platform : pcbios i386, pcbios x86_64, efi i386, efi x86_64.

Tiny PXE Server is serving by default pcbios ipxe.pxe and also, depending on the client architecture, serving the matching ipxe efi version.

See below my config.ini and a custom wimboot.ipxe script.

Discuss it here.

If like me you have an old computer and dont want to install the Ubuntu update for Meltdown and Spectre ubuntu update :

  • sudo vi /etc/default/grub
  • add nopti to GRUB_CMDLINE_LINUX_DEFAULT (there should be a list of parameters already like « nomdmonddf nomdmonisw nomdmonddf nomdmonisw »)
  • sudo update-grub
  • sudo reboot

check that nopti is there with cat /proc/cmdline

On removable medias (such as USB disks), Windows can only access one partition at a time.
This is a driver limitation (which you can actually work around by using another driver but this is not the point of this article).

Here below one way to work around this.

First, lets select our device in CloneDisk and under the disk (right) menu : (1) put it offline, (2) delete disk layout, (3) create 2 (or more) partitions, (4) put your disk online.

Note that if you disk is already multi partitioned, you can skip the above 4 tasks and go the last part of this article which is about accessing the second partition.

Create one partition, and repeat this task once.

Once done (i.e partitions are created), it should looks like this once done (2 times 2 GB partitions).

In CloneDisk main window, put your disk online : windows should detect a new volume and offer to format it (if not, remove and reinsert media).

Create a folder named ‘part1’ (this is only a witness/indicator)

Now, lets see how we can access the second partition : Go back to CloneDisk -> Disk -> Partition Editor, select your second partition and « set as partition number 1 ».

Again, windows should detect a new volume (the previous volume ‘part 1’ has disappeared) and offer to format it (if not, remve and reinsert media) – unless you have skipped the first part of this article.

Create a folder named ‘part2’.

You can now switch back and forth between your partitions on your removable media by using CloneDisk -> Disk -> Partition Editor, select your partition and « set as partition number 1 ».

MkIso will create an ISO from a source folder.

Supports multi-boot iso : x86 and EFI.
Supports isolinux (checksum will be taken care of).
Tested successfully with Grub4Dos.

Mkiso is native (no external dependencies), standalone, built in on windows builtin imapi2.

MkIso is also part of CloneDisk.

Questions, feedback, requests welcome.

MkIso

Regards,
Erwan

Lately I decided to flash my Linksys wrt1200ac with dd-wrt as Linksys obviously dropped support for this nice hardware (no more firmware updates for a long time).
Not to mention that the vendor firmware is extremely basic (not to say limited…).

Once I had flashed the device with the proper firmware, next step for me was to monitor bandwidth from my domotic/monitoring box (jeedom).

The most obvious track was snmp (dd-wrt feature) – Helas, the snmp daemon does not implement counter64 snmp values so this is useless.
Next step was to use some curl/awk/grep script like curl -u root:password http://192.168.1.250/Status_Internet.asp, etc but the web pages heavily rely on javascript so here again, curl was a dead end.

I finally resorted to remotely read values from the device nvram using a script around ssh : not the most elegant way, but the only one I could work out.

The below will retrieve the day/month/year value from my Linksys wrt1200ac based on dd-wrt.
(Note, I had to use ssh-keygen & ssh-copy-id to be able to ssh without having to provide a password).

#!/bin/bash
read YYYY MM DD <<<$(date +'%Y %m %d')
#echo 'nvram get traff-'$MM'-'$YYYY
sudo ssh root@192.168.1.250 -q 'nvram get traff-'$MM'-'$YYYY | awk '{print $'$DD'}' | awk -F ":" '{print $1}'
